Description Apeksha 2015-06-30 05:43:36 EDT

Description of problem:
Consecutive volume start/stop operations when ganesha.enable is on, leads to errors

Version-Release number of selected component (if applicable):
glusterfs-3.7.1-6.el6rhs.x86_64
nfs-ganesha-2.2.0-3.el6rhs.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Create a 6X2 volume on the ganesha setup 
2. Start the volume and enable ganesha, volume gets exported
3. Stop/start the volume, volume gets unexported and exported
4. Again stop the volume, volume does not get unexported.
5. Now if we start the volume, showmount command hangs and times out

Actual results: Showmount command hangs

Expected results: Showmount command must work successfully

Comment 2 Meghana 2015-07-01 01:35:09 EDT

gluster vol stop is expected to unexport the volume and the following start is expected to export the volume. This behaviour works fine for one iteration.
The second iteration, the export file is created in a slightly different format.
Due to this, the volume can never be unexported after this operation. Even 'ganesha.enable' off will not work after this.

I have RCAd the problem and will send in a fix soon.

Comment 6 Apeksha 2015-07-08 06:46:34 EDT

Consequitive start/stop now exports/unexports the ganesha volume
